About this 0.81ct natural round diamond

This 0.81ct natural round sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2507477102. Listed at 10 retailers as of October 30, 2026, with prices from HK$11,801 to HK$31,180, a HK$19,380 spread on the same certified stone. NZ Jewellers lists it at HK$31,180. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
